FunFunNone Created by: DaniaCreated on: 03-05-13 17:31 Strong acids will most likely be the colour... red 1 of 23 Strong alkalis will most likely be the colour... purple 2 of 23 The concentration tells us.... how much water the acid contains 3 of 23 if something is corrosive it will... attack and destroy living tissues, including eyes and skin 4 of 23 if something is highly flammable it will... catch foie easily 5 of 23 if something is explosive it will... explode when it is set alight 6 of 23 if something is oxodising it will... provide oxygen which will make other materials burn more fiercely 7 of 23 if something is toxic it may... cause death. it might be swallowed, breathed or absorbed in by the skin 8 of 23 nuetralisation is... when an acid and an alkili are balanced out to make a nuetral solution 9 of 23 you can test for CO'2 because it will... make limewater clody/milky and it will make a lit splint go out 10 of 23 you can test for hydrogen because it will... make a lit splint pop 11 of 23 hydrochloric acid + magnesuim produces... hydrogen gas 12 of 23 nitric acid + carbonate produces produces... carbon dioxide gas 13 of 23 hydrochloric acid + magnesuim carbonate produces... carbon dioxide gas 14 of 23 sulphuric acid + magnesuim produces... hydrogen gas 15 of 23 burning always requires... oxygen 16 of 23 combustion is... burning 17 of 23 fuels are made up of... hydrocarbon and oxygen 18 of 23 dilute acids are... concentrated acids which have had water added to them 19 of 23 concentrated acids contain... little or no water 20 of 23 The 7 things that tell us that a chemical reaction has taken place are... it's irreversible, it starts to bubble, changes colour, form solids, gives off a smell, the temperature changes, gives out light 21 of 23 carbon dioxide is formed when... carbonate reacts with an acid 22 of 23 the difference between a physical and chemical reaction is... physical-reversible chemical-irreversible 23 of 23
